I picked up and had a noodle on one of my guitars earlier today. It doesn't happen often enough as I always seem to find something more important to do. The thing I find to do is never actually that important.
I decided that I'd dig out my old SoundCloud account as I had recorded a few bits. None of them very good but it was great to learn new things. I really enjoyed playing about with the recording process; it was as much fun as the guitar playing.
One such recording was Behind Blue Eyes but I never actually got around to finishing it. I'm not sure if I still have the original tracks so would need to start from scratch
